Migraine relieved by Indomethacin?

So headache specialist gave me indomethacin 100mg suppositories to try on the last appointment (plus a couple other things) and today was the first day I tried them. Woke up with a pounding throbbing head (left side only), used a imitrex nasal spray and had no relief (very very untypical) so I gave up sleeping and started moving around (sometimes it’s neck/back spasms that improve once I’m walking around and allows the triptans to work, nothing. No change after 5 minutes and pain increased and since I don’t need to drive today I thought i would giv ethe new ones a try before heading into the ER (10/10 pain). And within 10 minutes the pain was GONE 100%, end of migraine, no hangover symptoms which is also very usual for my chronic migraines. Which of course I looked up hemicrania continua which I had read about over the year and knew it responded to indomethacin. But ..... I don’t fit the diagnosis. My migraines switch sides constantly, my daily headache is normally two sides and almost never get runny nose/eye, dropping etc. So .... can indomethacin work that well for regular migraine attacks since it’s an anti-inflammatory? I can’t find yes or no anywhere, all the articles talk about is people with so called chronic migraine (especially iratractabke like me) being actually hemicrania continua. It’s still 2 months away from my headache specialist appointment which I will ask then but hoping to find an answer before that.
